Review on 🔌 Autolite XP5702 Iridium XP Spark Plug - 1 Pack (Automotive Replacement) by Jeremy Yuusuf

Good at first. They fit Forte SX 2014-2016 (1.6 Turbo). Being a notch colder they are a good solution for this car as the OEM spark plugs are too hot and cause premature detonation. I put them on and started the car. Smoother idle, better performance in cold weather and most importantly, much better under heavy loads when the engine is hot on a hot day. Now for the bad. First, the gaps are too big. If you put it as a gap at the factory, the car will have no power. Second and most important - NOT the last. Mine broke after 1000km of careful use. Yes, a thousand miles. Something is wrong with them as many Forte SX users complain about crashes. Most often, ceramics break and fall to the ground. This will cover the electrode and cause misfire. I strongly advise against staying away from this brand. I didn't believe myself, but I learned my lesson.
